- clamping screw presses in the contacting of at least one conductor on the intermediate piece, that this is deformed and thereby at least one conductor is fixed substantially tubular metal insert, and wherein the clamping screw and / or the intermediate piece for contacting at least Having a conductor facing convex surface.
- a terminal is provided with such a device, as well as a lamp operating device, a high-pressure ignition device and a lighting system.
